工业上DMF的生产原料DMA主要由甲醇的胺化反应获得(Scheme 1a),但该过程因热力学平衡原因,会同时产生甲胺(MMA)和三甲胺(TMA),附加值均低于DMA。其中,MMA可经循环利用合成DMA,但TMA再利用的成本较高。此外,TMA相比于MMA和DMA,其热力学更稳定、产量更高。平衡混合物中其他胺类化合物的生成严重限制了工业上甲醇胺化...

An Improved Synthesis of Carbazoles via Domino Reaction of N‐Protected‐2‐methylindoles with DMF‐DMA/DMA‐DMAAn efficient synthesis of carbazole analogs has been achieved via interaction of N ‐protected‐2‐methylindoles with N,N ‐dimethylformamide dimethylacetal as well as N,N ‐...
A facile synthesis of biaryl systems has been achieved involving three-component coupling reaction of ethyl β-arylcrolonate, DMF.DMA and electron deficient alkyne. Antibacterial and antifungal activities of a representative biaryl compound are also reported....
This paper reports on the calorimetric study of the reaction between hydrated lanthanoid trifluoromethanesulphonates and DMF in ethanolic solution which was carried out in order to determine the dissolution standard enthalpies and acid-base enthalpies for the reaction of the hydrated salt with DMF...
